The Role

We’re looking for a

Full Stack Engineer

who’s fluent in

React Native, TypeScript, Node.js

and thrives in fast-moving, lean startup environments. You’ll own development end-to-end — from crafting smooth, responsive mobile experiences to building robust backend systems that power them.

You’ll play a key role in shaping a

new financial product

that blends Web2 reliability with Web3 innovation, bringing stablecoin-enabled credit cards and intelligent financial tools to a global audience.

This role is ideal for someone who loves shipping fast, solving problems across the stack, and working closely with design and product in a small, high-trust team.

What You’ll Do

Build and maintain mobile applications using React Native with a focus on performance and user experience.

Design and implement backend systems using Node.js and TypeScript for APIs, data flows, and business logic.

Collaborate closely with product and design to turn concepts into working, user-ready features.

Operate like an owner: make decisions, prioritize well, and ship quickly without sacrificing quality.

Work across the stack to ensure seamless communication between frontend and backend systems.

What We’re Looking For

5–8 years of professional software engineering experience.

Strong expertise in React Native (mobile app architecture, performance, debugging).

Deep backend experience with Node.js / TypeScript, and RESTful API design.

Proven ability to deliver quickly in lean, high-velocity teams.

A “builder” mindset — proactive, resourceful, and comfortable with ambiguity.

Nice to Have

Interest in AI and how it can enhance financial or operational products.

Curiosity about fintech, DeFi, or the Web2 ↔ Web3 intersection.

Familiarity with Web3 libraries
